Hi Sai,
Thanks for you reply. I did look into this post but don't believe it is the issue. My 1 cent rounding issue is not consistent. It will occur randomly on an invoice. For example recently there were lots of 1 hour labour billed and one 1 hour labour showed as $86.36 ex GST and one showed as $86.37 ex GST. It will mostly show as $86.36 per unit ex GST, with the odd labour charged showing $86.37 ex GST. I understand it is a rounding issue, however it is not consistent. It randomly rounds up here and there through an invoice which will have 10 or more lines of labour charges. I have managed to fix the overall labour charge including GST with the actual selling price through the card and I have also managed to fix the overall total GST at the end of the invoice. So Total amounts are at least correct, it just isn't the best look to clients that the figure for ex GST will vary.
I will look into contacting live support.
Thanks.
